Kokako are essentially weak fliers. They move through the forest canopy by alternately gliding, during which they lose altitude, and hopping vigorously to regain it, utilising forward momentum for both long and high jumps. As we watched, this bird, its long legs working like springs and its stubby wings generating extra lift, made an upward traverse across several vertiginous gaps from a kamahi to a taller tanekaha. Once it had zigzagged to the tanekaha’s summit, it stopped and craned into the wind, before launching itself into space and out of sight, this time for good.

Overview
The South Island kōkako (Callaeas cinereus) is a possibly extinct forest bird endemic to the South Island of New Zealand. Unlike its close relative, the North Island kōkako (C. wilsoni), it has largely orange wattles, with only a small patch of blue at the base, and was also known as the orange-wattled crow (though it was not a corvid). The last accepted sighting in 2007 was the first considered …

Although the genus Callaeas is masculine, the species epithet cinerea is not masculinised to mat…
